Configuring Ip Unicast Routing - Cisco IE-4000 Software Configuration Manual

Configuring IP Unicast Routing

This chapter describes how to configure IP Version 4 (IPv4) unicast routing on the Cisco Industrial Ethernet Switches,
hereafter referred to as switch.
Note: Dynamic routing protocols are only supported on switches running IP Services feature set. Static routing is
supported on Lan Base feature set.
For more detailed IPv4 unicast configuration information and complete syntax and usage information for the commands
used in this chapter, see documents listed in the

Information About IP Routing
In an IP network, each subnetwork is mapped to an individual VLAN. However, network devices in different VLANs cannot
communicate with one another without a Layer 3 device (router) to route traffic between the VLAN, referred to as
inter-VLAN routing. You configure one or more routers to route traffic to the appropriate destination VLAN.
